Abstract
The invention relates to the reproduction of a television signal on a distant reproduction device. The received television signal is encoded and transmitted in a digital data format over a communication link to the reproduction device. The reproduction device decodes the received video information for display on a display screen. The invention is particularly intended for use in mobile vehicles, coaches and trains, where the signal strength of a received television signal during travel is continuously varying and signal distortions occur frequently. In order to reduce the effect of signal distortions on the perceived image and audio quality, the invention inserts a compressed pre-stored video or audio data into the data stream transmitted from the television receiver to the reproduction device upon detection of a television signal distortion. Thus, the decoding procedure at the display device can be maintained in spite of a received television signal of insufficient signal strength.
